Description

[Detailed Description of the Invention] [Industrial field of application] This invention transfers a container containing a whole blood sample or the like to a target analyzer along a container supply line, and the analysis is completed by the analyzer. The container transfer device configured to transfer the prepared container to the container stacker again in the container supply line, and in particular, reinspect the container containing the sample requiring reinspection at least twice. Therefore, the present invention relates to a container transfer device capable of significantly reducing the frequency of manual re-inspection.

[Prior art and its problems] As is well known, from the viewpoint of reducing manual work and preventing blood infection, a container containing a blood sample or the like is automatically sent to a target analyzer. Conventionally, various types of container transfer devices have been proposed that are configured to automatically transfer a container for which analysis work has been completed to a container stacker.

However, in the conventional container transfer device described above, the container containing the blood sample and the like is automatically sent to the target analyzer, and the container after the analysis work is automatically transferred to the container stacker. Most of the containers that are designed to be sent to
After all the analysis work is completed, the work process of manually searching the container stacker and sending it to the analyzer again is required, so this work is very complicated and the analysis is always running. In the case of an instrument, due to some environmental changes, voltage fluctuations, etc., even if it is a normal sample, an erroneous determination that "retest is required" is often made. However, there is a problem in that the reliability of the measurement accuracy is impaired.

The present invention has been devised in view of the current situation, and the purpose thereof is, of course, that a container containing a sample can be transferred to an analyzer without any manual operation. Even if a sample has been determined to require retesting, in order to determine if this is due to an error on the analyzer side, retesting can be performed again on the analyzer before returning the container to the container supply line. SUMMARY OF THE INVENTION It is an object of the present invention to provide a container transfer device configured to obtain analysis results as quickly as possible by significantly reducing the frequency of retesting.

[Means for solving the problem]

In order to achieve the above object, in the present invention, a container containing a blood sample is transferred to a target analyzer along a container supply line, and the container whose analysis is completed by the analyzer is A sub-line is formed between the container supply line and the analysis device on the technical premise of a container transfer device configured to transfer to the container stacker again in the container supply line, and the sub-line is the container supply line. While sequentially transferring the container flowing through the line to the analyzer, the container after the sample dispensing work by the analyzer is transferred to the re-inspection standby line, the container stocked in the re-inspection standby line, When the inspection by the analyzer is determined to be normal, the transfer robot is transferred to the container supply line, and when the inspection by the analyzer is not normal, the transfer robot is transferred. The container containing the sample that has been transferred again to the sub-line via the container and that has not been tested twice by the analyzer is transferred to the container supply line via the transfer robot. It is characterized by being configured as described above.
